Edge retention and hardness aren't necessarily related, as a harder material might chip more easily, this is why steel knifes are annealed efter hardening.

I guess the problem is peoples definition of "precision" for most DIYers and hobbyists, your machine is more than precise enough, for machinists, it's not even close.

Corundum (sapphire and ruby) are 9 on the hardness scale. Only being beat by diamonds which are a 10 however the difference between a 9 vs 10 is bigger than a 1-9
